RISSeismic Behavior and Design Approach of Variable-Damping Self-Centering Braced Frame
Publisher: ASCE
Abstract: In this paper, the seismic performance and resilience of a 15-story variable-damping self-centering braced frame (VD–SCBF) were analyzed. The interstory drift ratios (IDRs) of the VD–SCBF are similar to those of the ...
Modeling of Disc Spring Self-Centering Energy Dissipation Braces from Inactive State to Design Limit State
Publisher: ASCE
Abstract: This paper focuses on modeling the hysteretic behavior of disc spring self-centering energy dissipation braces (DS-SCEDBs) from the inactive state to the design limit state, and proposes two restoring force models for ...
Seismic Analysis of a Self-Centering Braced Frame in Pseudodynamic Tests: Response Characteristics, Brace Contribution, and Damage Evolution
Publisher: American Society of Civil Engineers
Abstract: This study investigated the seismic performance and self-centering behavior of a three-story steel frame equipped with self-centering brace (SCBs) using pseudodynamic tests aided by OpenSees version 2.5.7 and OpenFresco ...
Design-Level Seismic Estimation of Self-Centering Energy Dissipation–Braced Frame Structures with Partial Recentering Capacity
Publisher: American Society of Civil Engineers
Abstract: Self-centering (SC) techniques have attracted widespread interest for the improvement of the seismic resilience of building structures. One typical representative is the self-centering energy dissipation (SCED)–braced frame ...
Modeling of Magnetorheological Self-Centering Brace
Publisher: ASCE
Abstract: The self-centering brace (SCB) is a high-capacity structural component for lateral force resistance and recentering. This paper focuses on modeling the magnetorheological self-centering brace (MR–SCB). Full-scale cyclic ...
